Seeing a rat or seeing droppings is the #1 sign you have a rodent issue.
Other rat detection signs:
- Destruction to food or property (particularly gnaw marks).
- Erratic pet behavior.
- Neighbors also complaining about rodent issues.
- Find oily 'rub' marks on baseboards and walls.
If rat is not caught in 2-3 days, unset trap, place trap in alternate location where rat activity is suspected, and then reset the trap.
Place trap near signs of rat activity. Some typical high rat activity areas are along walls in garages, attics, and basements.
